Spindle Direct or with Belt
The difference between high speed straight junction spindle and cnc belt spindle:
1、High speed straight spindle
Belongs to the rigid connection, for the motor output of the POWER can be fully expressed in the spindle characteristics, high mechanical efficiency, in the spindle movement, the coupling plays an indispensable role, coupling calibration is good or bad enough to affect the accuracy of the spindle movement, if the coupling calibration is not good enough to spindle to produce the following effects, the spindle temperature rise sharply, the spindle vibration is too large, the spindle deflection is too large, machining accuracy is poor, and even the spindle Even the spindle burns out. High-speed direct spindle that is similar to the three-axis motor and ball screw connection, the spindle motor is placed on top of the spindle, the motor and the spindle are connected by a high rigidity backlash-free coupling, and the rotation of the motor end is transmitted to the spindle through the coupling, which is the direct spindle.
2、Belt type spindle
Belt-type spindles use a belt to transfer the movement of the spindle motor to the spindle, the advantages of which are: less vibration than gear-type spindles, easy to assemble, and the disadvantages of which are high noise at high speeds, and belt tension is not easy to control.
